In constructing a machine embodying the invention a suitable main frameis provided which comprises two upright main members d and. a that areadapted to rest bn a lloor or upon timbers, a pair of transverse membersb and b, connected to the tops of the upright members, to the upper rearparts of the upright mem-- bers, and such other Yransverse members asmay be desired, which are omitted in 'the drawings in 'orderto avoidobscuring other` parts. A pair of tables d' and d are arranged asuitable distance apart and attached to the main membersnJ and e in gapsin the for-- ward portions thereof asparts of the frame, and,track-rails e and e', preferably composed of l.-section angle-iron, aresecured to the opposing edges of the tables for supporting the palletsl' etween the tables, it being designed that the pallets shall be placedon the rails at the left-hand side of the machine and to nieve on therails to the righhnand side of the machine, there to be lifted from therails. Obviously the rails may be provided with rollers, if desired., onwhich the pallets may move. Otherwise the palletswill slide on therails` j A. suitable number of reetangfularpallets H are provided. thatare adapte to rit on the rails e and c between the tables d and d, itbeing designed that three pellets may rest on the rails at onetime. Eachpallet has e suitable number of apertures f, Fig. ll, through whichcores may-be proleetecl from below when it may be desired to make hollowblocks. lfVhen solid blocks are to be made, the pallets obviously willnot be apertured. They are all preferably composed of wood. and may besuitably reinforced with metal,

if desired. Each pallet is slightly larger in plan than the blocks thatare to be formed thereon.

An endless belt l is arranged in a plane between the rails e and e andextends arallel therewith over two wheels g and g, tnat are mounteVbelow the ends of the tables d and d one of the wheels beinfhiI secured.to a rotative shaft lt and adapted to drive the belt in the direction of th e arrows therese. The bel t is preferably formed as a metallicsprocket chain. .A rotativo shaft 'i is supported by the maehinedramenear an end of the table d', and it is connected with the shaft .71, bybcvelgear wheels j and j. A sprocket-wheel l: is secured to the shaft 'iand connected by a chain-belt Zwith a sprocket-wheel k, that is sem-.rodto a coLmter-slraft m, v-fhich is mounted in the lower rear portion ofthe nntchinw frame. Vl`herefmge when the shaft 'm rotates the belt iwill be mieiuterl.. l? or rmeratiug `the shaft m perimlieall'y agear-wheel 'It is se cured thereto that is connected by a a transversemember c, attached.

wheel p, which is mounted rotatively on a main shaft q, that is mountedin the frame parallel to the shaft m, the wheel p being provided withclutch mechanism whereby it may be periodically lockedto the shaft g,the latter having a pulley r secured thereto to be belted to anysuitable engine or drive-pulley, so that the main shaft may rotatecontinuousl)T when the machineis in operation. The endless belt l isprovided with a suitable number of projections s, that are adapted toengage the tail ends of the pallets in order to move the pallets alongthe track-rails c and e', while the belt extends beneath the pallets. Itwill now be apparent that a pall t may be placed upon the track-railsand be oved to 'a position midway between the members aand a of theframe, Where the pallet maybe stopped, and serves as the bottom of amold, while a stone or block may be formed.

The mold comprises in addition to the bottom a movable mold-front J,that is suitably guidedand supported upon the table d, 'a movablemold-backl K, that is supported upon the table d', and two mold ends Land L, which are attached' to the mold-back by means of hinges t, eachmold end being' connected at an end thereof to an end of the mold-bach-The' mold-front J includes a member u or a member u', Fig. 9, againstwhich the mold ends are stopped and gagged when. closed, the membersbeing removable and of difierent patterns,` so as to form the frontfaces of the blocks in various patterns. A pair of curved operating-armsM and M are secured to the mold-front J and extend forwardly over thetable al and downwardly and rearwardly under the tables d and d', therear ends of the arms beingl connected by rods lv to rocker-arms N and Nand also by rods w to rocker-arms (l and U, the rockerarms N and N beingpivoted between their ends to the upright members a, and a. of theframe, and the rocher-arms (l and O being secured to a roch-shaft y,that is mounted in the frame members a and a. An arm 02 is secured tothe rock-shaft y for the operation thereof, and itis connected to a rod2, that is attached to a strap 4() of an eccentric l, which is mountedrotatively on the countershaftvn and secured to a gear-wluael all forthe operation and control thereof, the gearwheel beingIv engaged by agear-wheel 42, that is mounted rotatively on the main shaft (l andprovided wi th clutch mechanism, so that it may be perodically lockedto"thc main shaft and be driven thereby. lt will beobvious,.tl'lereforo, that when the gear-wheel 42 is in motion the`mold-front d will bc moved ther-chgr through the above-1lescribed conncctions.

In practical use the machine will be fed with the plastic material froma suitable hopper and spout and controlled by an attendant or byautomatic means, as may be desired'. rl`he-main shaft g should be put inmotion and the mold closed on a pallet to receive the plastic material,the tamping-bars being elevated and in continual motion vertically, thetampingbars W being moved also laterally. Y yWhile the mold isbeing'filled the tampingbars will gradually raise the frame in whichthey are mounted, and when the mold is filled ,the attendant should.elevate the frame and tamping apparatus by means of the handle 112 andallow it to be held up by the latch 116. An empty pallet should beplaced on the rails c e. '.lfhen the attendant may draw the handleforward and strike oil' the surplus material by vthe blade 122 and thonpush the blade back to its normal position, in which act the arm 124uwill move the lower end o`f the lever 128 forwardly and through theintermediate connections cause the cone-sleeve 49 to connect thegear-wheel 42 with the main shaft g, so that the eccentric l) will beput in motion and move one-half of a revolution and open the mold. 'Themold end l] in swinging open will engage the arm 1110, and thereby shiftthe cone-sleeve 19' from the gear-wheel 42 to a connection with thegear-wheel p, and theren by start the countershaft fm, whereby the beltI will be put in motion through the intermediate connections and willmove the full pallet to the right-hand side and also move the emptypallet to the position that had been occupied by the full pallet. Duringthe opening movements of the mold the mold-front J will engage 'thelever 149 and cause the'gage-stop 146 to be depressed, so as to becomelatched. Then while the belt l moves the pallets a projection 152 willengage the latch 150 and release the gage-stop. Also whilethe mold isopening the core-head 73 will descend and permit the pawl 158 to contactwith the bar 153 ready to enter the notch 157 therein when the bar movesrearwardly. The advancing empty pallet will engage the lever 142, andthereby through its connections shift the connection of the cone-sleeve49 from the gear-wheel 42 to the gear-wheel p, so as to set in motionthe eccenn tric P, which will move one-half of a revolu tion and closethe mold and then be stopped by reason of the projection 159 engagingthe pawl 158, so as to release the bar 153 (which had become latched)and. permit .the spring 155 to push the bar into mid-position againstthe spring 156, thus holding the cone-sleeve 49 in mid-position. Duringthe closing of the lmold the mold-front f will carry the catch 12()av'ainst the arm of the latch 116 and release die v ertically-movableframe and permit it to lower the tamping-bars to repeat the moldingoperation, as before. let when moved into position at the mold will pushthe lever 142 far enough to cause the lever to be depressed below thebottom plane of the pallet, and then the pallet will be stoppedpositively by the gage-stop 1416, the belt I being stopped by thepallet. The automatic processes will thus be carried on each time theattendant operates the strike-ofi' blade 122. l

If desired, the strike off blade may be provided with deviccs'for theautomatic operation thereof, and also mechanism may beprovided forautomatically elevating the tam ing apparatus, so that the me chine may)e causer'. to operate continuously in an automatic manner.
